Word origin

直线 (zhíxiàn, "straight line") is formed from 直 (zhí, "straight") and 线 (xiàn, "line"), so its structure directly links the shape to the thing being drawn.

Usage tips

  • English mathematics often separates a line from a line segment, while everyday Chinese can use this word for both, with the context providing the distinction.
